Aspects are used in a similar manner to IHMN, but the game caters for larger sized groups (looks like Games Workshop sized battles that fall somewhere between skirmish and army size).
Models have recommended base sizes, have a 90 degree arc of fire to the front for single figures, and up to 180 for extended fire arcs for group elements (units).
Stats are Move, Fight, F Pow (Fight Attack Power), Dur (Durabilith), Size and BV (Build Value)
Standard move of 6" for humans
The rules for mad scientist leaders in the game seem heavily inspired by Girl Genius. The Sparks here are called Maestros and are themed according their branch of Secret Science.
Leader types (including the mad scientists) have a Sphere of Influence used for command. Some types of action require a model (or group) to be "within command" – within that radius – in order to perform the action.
The turn order for shooting and fighting (melee) is considered simultaneous. There is a roll for initiative which determines the order of movement to be slowest to fastest or fastest to slowest of the various subcategories of "who goes when". It's a bit unclear on the "my turn, your turn" order – how many models/groups you move a time.
Shooting takes into account lanes of fire. D6 is rolled per figure able to shoot – mutliple dice for rate of fire and bonuses. Fighting is similar – so looks like a bucket-of-dice game :)
Damage requires a "to wound" roll – similar to Games Workshop Toughness and less abstract/more crunchy than IHMN's Pluck.
Morale rules are included, and rules on how to build a faction
After that – the next half of the book details the kinds of forces in the game, based on type and which themed branch of Secret Science they belong to (e.g. Mechanicians or Ressurectionists).
Last few pages include a scenario generator, a list of aspects used in the game, and a 2 page summary of the tables and charts as a play aid.
